I explored that patch. It is not backported to 1.10 (obviously) since
other changes except for additional clean-up in vy_write_iterator_start()
look like refactoring (we push to 1.10 only bug fixes). It can't be
cherry-picked now since code is bit different and 1.10 lacks some
features (like heap helpers to determine whether heap node is linked or
not). So I suggest to leave my patch as is for 1.10 branch and backport
test case to master branch.
